GLSA-200907-04 : Apache: Multiple vulnerabilities

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200907-04
(Apache: Multiple vulnerabilities)

Multiple vulnerabilities have been discovered in the Apache HTTP
server:
Jonathan Peatfield reported that the
'Options=IncludesNoEXEC' argument to the 'AllowOverride' directive is
not processed properly (CVE-2009-1195).
Sander de Boer
discovered that the AJP proxy module (mod_proxy_ajp) does not correctly
handle POST requests that do not contain a request body
(CVE-2009-1191).
The vendor reported that the HTTP proxy
module (mod_proxy_http), when being used as a reverse proxy, does not
properly handle requests containing more data as stated in the
'Content-Length' header (CVE-2009-1890).
Francois Guerraz
discovered that mod_deflate does not abort the compression of large
files even when the requesting connection is closed prematurely
(CVE-2009-1891).

Impact :

A local attacker could circumvent restrictions put up by the server
administrator and execute arbitrary commands with the privileges of the
user running the Apache server. A remote attacker could send multiple
requests to a server with the AJP proxy module, possibly resulting in
the disclosure of a request intended for another client, or cause a
Denial of Service by sending specially crafted requests to servers
running mod_proxy_http or mod_deflate.

Workaround :

Remove 'include', 'proxy_ajp', 'proxy_http' and 'deflate' from
APACHE2_MODULES in make.conf and rebuild Apache, or disable the
aforementioned modules in the Apache configuration.
